invention relates to; and it is an object to provide, an improved siphon pipe adaptable to many uses, but especially designed for use as a portable irrigation pipe.

l ur'ther objects of this invention are to prov'ide a siphon pipe whichis easyto initially start; to provide a siphon pipe through which the flow can be readily regulated; and to provide a siphon pipe which holds its prime, i. e. will automatically reestablish flow if the water at the inflow end of the-pipe=recedes below the intake point and then suhse uently raises above such point.

Another --obiect of the "invention to provide a siphon pipe, as above, which comprises an inverted, generally -.U-shaped ,pipe formed at the lower ends of the legs thereof with upturned, trapforming goosenecks; the traps formed by said goosenecks being the means whereby the siphon will automatically reestablish its llow.

it is also an object of the "invention to provide a siphon pipe, of the type described, which incorporates means to assure of complete air escape or discharge when the pipe is initially primed.

A further object of the invention is to produce a simple and inexpensive device, and yet one which will be exceedingly effective for the purpose for which it is designed.

These objects are accomplished by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views:

Figure 1 is an elevation of the device as in use.

Figure 2 is an enlarged cross section on line 2-2 of Fig. 1.

Referring now more particularly to the characters of reference on the drawings, the improved siphon pipe is indicated generally at I and comprises a length of pipe formed in generally inverted U-shaped, with a normally horizontal center section 2 and outwardly and downwardly divergent legs 3.

At their lower ends the legs 3 are formed with upturned, trapforming goosenecks 4, with the upper or open end of each gooseneck extending a substantial distance above the lowermost point thereof.

Each of the goosenecks 4 is formed, on opposite sides and in partly crossing relation to the vertical center line thereof, with expanded, elongated blisters 5 for the purpose hereinafter described.

;3 Claims. (01. 1337- 20) Although "the-device may "be effectively put to on the other side of said bank there is an irrigation'ditch 8.

To transfer water from the ditch 1 to the ditch 8 by means of the described siphon pipe, the latter is manipulated as follows:

At the outset the entire "siphon pipe is sub merged in the water supply ditch '1, with the ends a of said pipe slightly elevated. This permits all air in the pipe to escape except a small amount which remains in-the goosenecks 4.

The center section 2 is then raised until the pipe is disposed-inaverticalplane, but with the goosenecks "4 remaining submerged. Upon such raising of the center section, the remainingsmall amount of air is exhausted from goosenecks 4 by being attracted toward the outside ends of the pipe by the expanded blisters, since the small bubbles of air tend to localize in these blisters and are then carried from the discharge end of the gooseneck with the flow of the water.

Thereafter the pipe is swung across the ditch bank 1 and disposed thereon in the position shown in Fig. 1; it being necessary to keep ends 9 and II approximately level to avoid enough water being spilled so that air could enter the pipe.

When the pipe is disposed in position the inflow end 9 thereof is below the surface ID of the water in the ditch 1, whereupon the siphon pipe immediately begins to function, and water delivers from the outflow end ll of said pipe into the irrigation ditch 8.

By reason of the portability and easy starting of the siphon pipe a substantial number thereof can be employed with facility for irrigating, and with a substantial labor saving as compared to straight pipes which must be dug into the bank.

Additionally, the described siphon pipe can be easily adjusted to regulate the flow therethrough by manipulating the pipe so as to vary the elevation of the outflow end I l thereof. In this manner an accurate and regulated rate of flow can be attained without the use of stoppers or the like, as are conventionally used.

It should also be noted that where a multiplicity of the siphon pipes are used along a ditch bank to irrigate row crops or the like the pipes can be regulated, without difficulty, to each deliver the correct flow. whereby to accomplish even distribution of water over the entire area being irrigated, notwithstanding the variable porosities of the soil.

Another advantage of the described siphon resides in the fact that once the pipe is primed and set in place, it will automatically reestablish flow therethrough even though the water surface II) in the supply ditch falls below the inflow end 9 and then subsequently raised above said end. This automatic reestablishment of the siphon flow is accomplished through the use of the upturned gooseneck traps 4. With existing siphon pipes, the same require manual starting thereof each time a siphon break occurs and this presents a serious problem, as it is difficult to start the pipes fast enough to prevent the supply ditch from overflowing. On the other hand, the present invention assures of automatic reestablishment of flow in the siphon pipes even though.

there may be temporary failure or loss of supply in the ditch 1. Should the siphon be of too large a size to readily handle, it may be a fixed installation. In such case the initial prime will be accomplished by force feeding liquid through the pipe, and permitting of air escape from the top of the siphon through an air vent valve (not shown). However, in such an installation the upturned, trapforming goosenecks would be included for the purpose of reestablishing flow in the manner described above.

From the foregoing description it will be readily seen that there has been produced such a device as substantially -fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as set forth herein.

4 lowing is claimed as new and useful, and upon which Letters Patent are desired:

1. A siphon pipe including a center section having downwardly extending legs on opposite ends thereof, and upturned goosenecks on the lower ends of said legs; each gooseneck having a laterally outwardly expanded blister thereon adjacent the low point of said gooseneck and extending therefrom in a direction towards the adjacent end of the siphon.

2. A siphon pipe including a center section having downwardly extending legs on opposite ends thereof, and upturned goosenecks on the lower ends of said legs; each gooseneck having laterally outwardly expanded blisteres thereon on opposite sides and intermediate the ends of said gooseneck, such blisters extending from the low point of each gooseneck in a direction towards the adjacent end of the siphon.

3. A siphon pipe including a center section having downwardly extending legs on opposite ends thereofyand upturned goosenecks on the lower ends of said legs; said goosenecks being disposed in the same vertical plane as the remainder of the pipe, and each gooseneck having laterally outwardly expanded blisters thereon on opposite sides and intermediate the ends of said gooseneok,-such blisters extending from the low points of each gooseneck in a direction towards the adjacent end of the siphon.
